I've watched the canonical Andrew Ng video on the subject but I'm trying to translate those concepts into java, and I'm not quite sure I did it right.
The thing that's confusing me is, I made a toy ...

I'm need to create boxplots to analyse and evaluate test results. Since I program in Java this answer convinced me to use JFreeChart. The BoxAndWhisker chart seemed similar to what I wanted.
I spent ...

Basically, what I need is to calculate the correlation coefficient for 2 arrays, which I can ...

Python is plenty of ML libraries (like the great scikit-learn). Is there any good for java/scala, containing many algos (regression, classification, clustering, cross-validation, feature processing), ...

I am using the Weka API for my research about document classification. I wish to apply Latent Dirichelet Allocation on my dataset followed by using a classifier in Weka. However, it is not so clear to ...

I grabbed an implementation of FuzzyKMeans (FuzzyCMeans) from the nightly build of the Apache Commons Math library, but I now realize I need to use Cosine Similarity instead of the Euclidean Distance. ...

I want to compute the p-value of a single numeric value drawn from an arbirtary distribution.
The p-value should be comparable to p-values that have been computed with single distinict values drawn ...

I'm looking for implementations of online learners. I guess that is possible with AdaBoost. Where you train the model and then you modify it by adding later more training data. However you don't have ...
